The Computer System

When we talk to our friends , families and also strangers , we just refer to the words 'data' and 'information' as the same thing . But it's not , in fact it really is this :

                       Data + Structure = Information

The computer will process data , add the structure and give us information .

What is a computer ?

A computer is a machine which can be programmed to accept the data we put in and gives out information .

                       Input - Process - Output 

We put our data in the computer (input) , then the machine will process it ,finally information comes out
(output).

So we can just say that a compute is a device that accepts input , processes data ,stores data and produces output .

Input is the process of entering data in the computer .Some examples used for inputting data are the keyboard , mouse and the modem.

Output is getting processed data out of the computer . Either the computer will display the data on the monitor screen which we call soft copy  or either sends the data to a printer and we call that hard copy.
